SEA'IVI-RUBBER FOR BOOTS AND SHOES.

SPECIFICATION forming part of Letters Patent No. 374,655, dated December 13, 1887.

Application filed October 4, 1887. Serial No. 251,394. (No model.)

To aZZ whom, it may concern,.-

Beit known that I, CHARLES H. GARR, of Portsmoutlnin the county of Rockingham, State of New Hampshire, have invented a certain new and useful Improvement in Seam- Rubbers for Boots and Shoes, of which the following is a description sufiiciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the saine, reference being had to the accompanying drawings, forn1- ing part of this specification, in which- I Figure l is a side elevation of my improved seam-rubber, some of the parts being shown i5 in section; Fig. 2, an end elevation of the same, some of the parts being shown in vertical section; Fig. 3, avertical longitudinal section with the standard, bed, and shafts broken off; Fig. 4, a vertical transverse section taken on line x :i: in Fig. 3, and Fig. 5 an elevation of the guide detached.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

- My invention relates more especially to means for rubbing down or finishing the seams of boots and shoes; and it consists in a novel construction and arrangement of parts, as hereinafter more fully set forth and claimed, the object being to produce a more effective and otherwise desirable device of this charac ter than is now in ordinary use.

The nature and operation of theim provement will be readily understood by all conversant with such matters fromthe following explana tion.

In the drawings, A represents the bed of the machine, B the standard, and F the arm, these parts being similar in shape to those of a sewing-machine, the standard being secured to the bedA by screws 60. rlwo circular plates, a", are rigidly secured, by means of screw-bolts z, to the outer end of the arm F, (see Fig. 3,) and are separated by a plate, o, which is provided in its lower portion with a circular opening, t, as shown in Fig. 4. The plates x are providedV on their outer edges with flanges m, and disposed on said plates between said flanges and the plate c, so that 5o they will easily revolve thereon, are two rings,

10, having the outer edges of their peripheries serrated to form gears 6l, and their inner edges beveled inwardly toward the plate c, as best shown at 62 in Figs. l and 3. f

A horizontally-arranged shaft, D, has one of its ends journaled in the plates 'x and its other in the standard B, pulleys E being dis posed on said shaft, by means of which the mechanism herein described is driven.

A rubbing or burnishing wheel, H, is. Se- 6o cured to the shaft D between the plates x m and within the opening t of the plate o. (See Fig. 4.) v

A horizontally-arranged shaft, G, is journaled in standards b on the arm F of the stand- 65 ardB. (See Fig. 1.) On the outer end of the shaft G are disposed vgears d, said gears being so arranged that their teeth will intermesh with the teeth 6l of the rings w. The shaft Gis driven by a worm-gear, K, worm 75, shaft 76, and bevel-gear J, said gear intermeshing with a. corresponding bevel-gear, 77, on the shaft D. (See Fig. l.)

A vertically-arranged rod, f, is fitted to slide in a socket, g, formed in a block, P, secured to-the bed-plate A directly under the plates w x o. The rodfis provided with a U- shaped head, h, in which are journaled two bedwheels', k, by means of stub-shafts z'. The wheels lc are beveled outwardly on their peripheries, as shown at 80, to correspond with the beveled edges of the wheels a: x, against which they press the leather when in use.

The lower end of the rod lf rests on the inner end of a metallic rocking spring, L, a thumb-screw, m, passing through the outer end of said spring into the bed-plate A, bymeans of which the inner end may be raised or lowered and the tension of the spring registered.

The bed-wheelsc are provided with annular rabbets p at their inner edges, which. when united, form a peripheral groove in said wheels, to admit a curved presser foot or bar, R, which extends horizontally under the rubbing-wheel H.

The presserfoot R hasa vertically-arranged rod or body, which is fitted to slide in the block P in substantially the same manner as the rodf, and its bottom rests upon the inner 10o end of a similar rocking spring, L2, provided with a screw, m2, by which its tension can be regulated.

A curved seam-guide, T, (see Figs. 4 and 5,) is adjustably secured to the forward edge of the plate c between the plates :v x, its lower end extending downward around said plate and close to the presser-foot B. The guide T is provided with two longitudinal slots, l5 and 16, through which screws 17 and 18 pass into the plate @,to keep the guide in position thereon.

A coiled spring, 2l, (see Fig. 5,) is disposed longitudinally in the slot 15, one end of which is secured to the screw 17 and the other to the body of the guide at the lower end of said slot, said spring acting expansively to press the guide downward toward the presserfoot R. y

The lower end of the guide T is provided with an open slot, 22, (see Fig. 5,) adapted to receive the scam of the boot or shoe upper as it is fed into the machine, a screw, 23, passing transversely through the sides of said slot, by means of which they can be brought or sprung closer together and the slot narrowed when desired.

In the use of my improvement the shaft D is set in motion by means of powerfapplied to the pulleys E, causing the wheel H to be rapidly revolved between the plates x x. Asthe shaft D revolves, it communicates motion to the shaft G by means of the gears K 77 and the worm 75, revolving the gears d,and therelby setting in motion the rings w w'on the plates :c :v in the direction of their arrow. The friction of the beveled portions of the wheels w upon the bed-wheels k cause them to be revolved inward in the direction of their arrow. By turning in the thumbscrew m and ,thereby elevating said wheels k the friction between them and the rings w may be increased as desired. The boot or shoe upper is inserted between the wheels k and rings w, with its seam in the slot 22 of the guide T, the under side of said seam resting on the presserfoot R. The rings fw feed the upper inward, so that its seam passes directly under the ruhbing-wheel H, the pressure of said Wheel upon the seam being regulated by means of the presser-foot B,its screw m1, and spring L, in a manner that will be readily obvious without a more explicit description.

The rubbing-wheel H is driven at greater speed than the rings w and bed-wheels k, thus thoroughly rubbing and finishing all portions of the seam as it is slowly fed under said wheel.

Having thus explained my invention, what I claim is- 1. In a machine for rubbing the seams of boots or shoes, the body A, provided with the standard B, having the arm F, in combination with the plates @c c, secured to said arm, rings w, journaled on the plates x, shaft D, j ournaled in the plates v and standard B, rubbing-wheel H, mounted on the shaft D, a presser-foot, bedwheels, and mechanism for revolving said shaft and wheels, substantially as set forth.

2. In an apparatus of the character described, the plates w, rings w, journaled on said plates, and the plate v, provided with the opening t, in combination with the gears d, the shaft G, gears K 77, worm 75, shaft D, carrying the wheel H, disposed in said opening, the presser-foot R, wheels 7c, guide T, and actuating mechanism therefor, substantially as set forth.

3. In an apparatus of the character described, the rod f, having the U -shaped head h, the beveled wheels k, journaled in said head, and provided with the rabbets 1J, in combination with the block P, having the socket g, rocking spring L, screw m, and bed-plate A, substantially as set forth. y

4. In an apparatus of w the character described, the presser-foot B, having the rod q, in combination with the block P, rocking spring L2, screw mi, and bed-plate A, substantially as set forth.

5. In an apparatus of the character described, the presser-foot R, provided with the spring L2 and screw m2, in combination with the shaft D, provided with rubbing-wheel H,

`rings w, plates w c, bed A, standard B, having the arm F, and mechanism for revolving said wheel, substantially as set forth.

6. In an apparatus of the character described, the bed-wheels k, rod f, and means for vertically adjusting the same, in combination with the rings w, plates c, rubbing-wheel H.

shaft D, and mechanism for revolving said wheels, substantially as set forth.
